I have an servo system and i want to know some datas:
1. Overall System Bandwith
This test we made with the servomotor whitout load. (smalest inertia)
We conect an sinus function generator to the servo controller.
The amplitude is adjusted so that we have nominal tourqe of the motor.
We see actual speed and set speed on a Oscilloscope.
We increase the frequency at the input to the phase shift between input
signal and output signal 45° amount to. (or the amplitude is 0.707 of the
input)
Is this correct ? Have you detailed information about this.
2. Bandwith of the speed and current controller.
Speed and current controllers are digitally executed with us. I think that the bandwidth of a
digital controller is only defined by the update time of the controller.
So the update time of the current controller is 64us and for the speed controller is 128us.
Do you know the exakt Bandwith of the both controller ?
Thank you for information.
